Description
RCV
O
Receive Data. CMOS level output for USB differential input.
/OE
I
Output Enable. Active LOW, enables the transceiver to transmit data on the bus.
When not active, the transceiver is in receive mode.
Mode
I
Mode. When left unconnected, a weak pull-up transistor pulls it to VCC and, in this
GND, the VMO/FSEO pin takes the function of FSEO (force SEO).
VPO,VMO/FSEO

Inputs to differential driver. (Outputs from SIE.)

Buffered version of D- and D+. Outputs are logic “0” and logic “1.” Used to detect
single ended zero (/SEO), error conditions, and interconnected speed. (Input to SIE).

Data+, Data-. Differential data bus conforming to the Universal Serial Bus standard.
SUSPND
I
Suspend. Enables a low-power state while the USB bus is inactive. While the
suspend pin is active, it drives the RCV pin to a logic “0” state. Both D+ and D- are 3-
STATE.
Speed
I
Edge Rate Control. Logic “1” operates at edge rates for “full speed.” Logic “0”
operates edge rates for “low speed.”
VCC
3.0 to 3.6 power supply.
GND
Ground reference.
